Who does SS non disc frames?

Struggling to find a decent frame second hand. Who produces Non disc Single Speed specific (track ends) frames? Anyone still make these?
It's for my last year's "racing" So light and XC ish.............

I have a 1X1 commuter, too heavy for my plans. Spot are great but States, so importing a frame is horredously expensive, same with Soma.
Moff again it's probably a bit heavy for what I'm after. I have year's of hoarded lovliness to fit.............
